グローバル変数コードの混乱

Question

あるクラスから別のクラスへのデータ入力に問題があり、グローバル関数が機能しないようです。私の助けが必要な部分は最後の機能ですが、コード全体があれば機能します。

あなたはグローバル変数を使用したい場合は、この実行する必要がありますおそらくあなたはすでにこれを知っていないもちろん

var1 = <some value> 
var2 = <some other value> 
s1 = <yet another value here> 

# then create your classes 

class Whatever(tk.whatever_you_want): 
    def __init__(self, arg1, arg2, whatever_arg): 
     global var1 #whis tells the function to use the variable you defined already in the module scope 
     local_var_1 = var1 * 100 # 

は、グローバル変数は通常、で開始する悪いと考えられていますしかし、私はそれがあなたのために大事だとは思わない。変数を変更して読み込んだら、それを追跡するのはあまりにも多くの場面で問題になるでしょうが、その大きなスクリプトを構築しているかどうかはわかりません。
